Did the upgrade and it's great but did anyone come up with a solution for the 73 models and the fuel pump reley problem. I saw where we should cut the wires and install a switch but isn't there a way to wire in a relay on the ON side of the ignition switch that would power the fuel pump relay. I'm not sure I want to mount a switch on the dash/center consual and them possibly forget to turn off the switch.

You can wire the relay to any accessory power source. You don't need a switch.
